The P03 recommended rescaling of the IAU200A nutation model to IAU2006 (see Coppola, Seago, and Vallado 2009) was not correctly implemented in the prior 1.4 releases, having missed its time dependence term. The resulting errors are below 40 μas in longitude and below 25 μas in obliquity the present era.
